17 Claims.

My present invention relates to bolstered handled cutlery, includingpocket-knives, hunting knives, daggers, kitchen knives, fish knives andthe like.

The purpose of this invention is to provide a new, improved, moreeconomical and more durable pocket-knife or other bolstered handledarticle of cutlery which construction involves the making of face platesof cheaper and stronger material, but of material that is capable ofbeing shaped, as by molding, to the precise shape and form for the faceplates of the knife, and which material is of such character that theconnecting and pivoting rivets can be projected through the premadeholes in the extended ends and even, where required, through theintermediate portion of the face plates and riveted over against or intothe face plates without breaking splitting or distorting the faceplates.

A further purpose is to provide a construction of a pocket-knife orother bolstered handled article of cutlery wherein the face plates areextended at both ends of the handle of the knife so as to receivetherethrough the connecting and pivoting rivets of the knife with saidpivoting and connecting rivets headed over into or on the adjacentportions of the face plates, and further to provide a construction ofthe kind indicated where hollow bolsters are provided to be slipped overthe said projecting ends of the face plates and thus form a bolsteredhandle simulating in general appearance the ordinary pocket-knife orother article of cutlery having a solid bolster.

A further purpose is to provide a construction of the type indicatedwherein the extended ends of the face plates are purposely made slightlyshorter and narrower than the end portions of the knife linings or theblade shank so that when the hollow bolsters are put in place thebolsters will project neatly into line with the adjacent outer edges ofthe linings or of the blade shanks near the ends of the knife.

A further purpose is to provide an article of the class mentionedwherein the connecting and pivoting rivets do not come through thebolsters and ed ends of the face plates, end such fastening i means arevery quickly brought into assembled and holding position.

A further purpose is to provide a knife construction wherein the faceplates have extended ends to be capped by a hollow bolster, and the saidextended ends are made thinner for a slight distance in from each sideof a face plate on the inner side thereof, and a knife wherein thehollow bolsters are provided with inturned flanges on their lateraledges, which flanges project into the clearance formed by the thinnedportion upon the under side of the projections.

A further purpose is to provide a knife wherein the face plates are madethinner on their outer extended ends that are to'be covered by thehollow bolsters, relative to the thickness of the adjacent portion ofthe ultimately visible face plates, so that when the hollow bolsters areassembled and fastened in place the adjacent inner straight edge of thehollow bolsters will substantially harmom'ze in elevation, or be flushwith, the adjacent portion of the exposed face plate, so as not to bedifferent in appearance or feeling from the old conventional form ofpocket-knife having solid bolsters.

Heretofore the conventional way of making a pocket-knife or similarbolstered handled article of cutlery has been to provide each side ofthe ends of the knife with solid bolsters of quarterspheroidal form soas to provide a rounded and crowned end leading back'in usually aslightly enlarging formation to the adjacent straight ends of the faceplates, and to have the pivoting and connecting rivets projected throughthese solid bolsters into subjacent portions of the linings and throughthe shanks of the blades, and through the spacing blocks if any be used,upon the knife. That construction involved the drilling or punching ofthe rivet holes through the solid metallic bolsters and thecountersinking of such holes, which drilling or punching andcountersinking if not properly performed resulted in unsightly bolsterrivets and required extra labor to repair or correct the defect;furthermore the riveting over of the ends of the connecting and pivotingrivets in the outer ends of the bolster holes was required to be donewith nicety and precision and had to be followed with grinding, glazingand buffing operations on the ends of the rivets and the adjacentportions of the bolsters with the result often that the riveting wasgreatly weakened and made less strong and durable.

The solid bolsters had to be of relatively expensive material and ofmaterial that would take a permanent polish no matter how much thebolsters had to be trimmed down and finished oif adjacent the rivets.

The purpose of this invention is to overcome the difliculties abovementioned and provide a construction that is mechanically acceptable tothe user and in fact, stronger and more durable in use, and at anappreciably lower cost.

A further specific purpose is to provide means upon the hollow bolsterthat will cooperate with means upon the face plate or other adjacentportion of the knife so as to automatically permanently lock the bolsterin place when it is slipped on to the end of the knife.

While the drawings illustrate and the specification describes in greaterdetail my invention applied to a bolstered handled pocket-knife, it willbe understood that such illustration and description is simplyillustrative and not a limitation of my invention, which is entirelyapplicable to other articles of cutlery having a bolstered handle.

Further purposes and advantages of this invention will appear from thespecification and claims herein.

Fig. 24 is a plan view of the broad side of a hunting knife embodyingthis invention and Fig. 25 is a View of the back edge thereof, but withthe front end of the handle in central longitudinal section.

Referring to the drawings in a more particular description and first toFigs. 1-19, it will be seen that the knife here shown has two outerlinings it, an intermediate lining [1, two blades 18, a spring I9 foreach blade, a pivot pin or rivet 20 for holding the shanks 2! of theblades to one end of the handle, and a connecting rivet 22 at the otherend of the handle and an intermediate connecting rivet 23.

The knife here shown is equipped with two blades, both mounted at oneend of the handle, but it will be obvious that the invention is equallyapplicable to a single-bladed knife (in which case the intermediatelining I! would not be used) or to a knife having its blades pivoted tothe opposite ends of the handle. In the particular knife illustrated theremote ends of the blade springs serve as spacing blocks to hold thelinings apart the proper distance at that end of the knife as isconventional practice; but my invention would obviously be applicable toa knife where a separate spacing block was used, and also of course to aknife where a blade or blades are located at both ends of the knife sothat the shanks of such blades would hold the linings apart without theaid of spacing blocks.

All of the parts so far mentioned are of conventional form and sorequire no further or detailed description.

The parts mentioned are assembled in place upon one another with thepivoting rivet 20 piercing the ends of the outer and intermediatelinings and with the intermediate connecting rivet 23 piercing theintermediate and outer linings and the intermediate portion of the bladesprings, and with the connecting rivet 22 piercing suitable holesprovided in the other extremity of the linings and the block ends of thesprings. At this stage of assembling both ends of each of the rivets areleft projecting outward from the parts of the knife through which theyhave been placed, that is without the ends of the rivets being cut offor riveted down.

The two face plates 24 are alike in formation and construction exceptthat in the usual way one face plate is for one side of the knife andthe other for the other side of the knife, and accordingly one detaileddescription of the face plate will suffice.

In my invention a, face plate consists of the long full-width andfull-thicknessed central portion 25, being the portion of the handle ofthe finished knife that is visible when the knife is completed, that isthe portion of the face plates that is between the straight inner edges26 of the hollow bolsters 27 hereinafter more particularly described,and which bolsters are slipped over the end extensions 28 at each end ofthe face plates 24. Beyond each end of this central portion the faceplates are provided with end extensions 28. These end extensions are alittle narrower laterally and a little shorter on their rounded endsthan the adjacent end portions of the outer linings It. The purpose ofthis reduction in extent and length of the end extensions 28 is so thatwhen the hollow bolsters 21 are slipped onto the end extensions 28 ofthe face plates, the side edges of the bolsters will come neatly evenwith the side edges of the ends of the outer linings and so that therounded ends 29 of the said hollow bolsters 21 will come even with therounded outer ends 30 of the outer linings I6. The central portions .25of the face plates will closely fit the width and usual slight curve ofthe edges of the outer linings.

These face plates will preferably be made of a plastic material that canbe readily shaped to the desired precise size, shape and formationincluding the required rivet holes by a molding process. This materialis not only plastic, that is moldable, but also it has a proper amountof resiliency or elasticity so that the ends of the rivets can beriveted down into or onto or flush with the countersunk holes made inthe ends and intermediate portion of the face plate as indicated in Fig.4, without danger of breaking, splitting or damaging the face plates.

A further advantage of the plastic face plates is that they can bereadily made in desired colors or combinations of colors and are morecomfortable to the hand than most materials heretofore used on theoutside of knife handles.

It will be understood however that face plates having the substantialshape of the face plates shown in the drawings and herein described asmade primarily from plastic material may be made out of other materialby properly shaping, cutting or grinding the same, without departingfrom the spirit of this invention.

After the two face plates 24 are assembled upon the knife as shown inFig. '7, and the projecting ends of the end rivets are riveted down intothe preformed countersunk outer ends of,

the holes in the face plate with said rivet heads slightly crowning overadjacent portions of the face plates, the hollow bolsters 21, of whichdetailed views are shown in Figs. 8, 9 and 10, are slid onto each end ofthe face plates. These hollow bolsters, as shown in the side views 8 and8,

are of the conventional bolster outline having a substantiallysemi-circular outer end 29 and with their inner straight ends 26 adaptedto neatly join the transverse straight shoulder 32 provided at each endof the thickened central portion 25 of the face plate 24. The side edges33 of the bolsters that extend from the practically semicircular roundedends thereof back towards the straight inner ends 26 of the bolsters arepractically straight but have a slight diverging taper or curve, so thatthese side edges 33 of the bolsters will register neatly with theadjacent side edges 34 of the outer linings and will lead harmoniouslyto the adjacent side edges 3535 of the nearby central portion 25 of theface plate.

The preferred and most convenient method of readily securely fasteningthe bolsters 21 to the end extensions 28 of the face plate 24 is toprovide the bolsters, at their edge portions 33 that lead back fromtheir rounding end 29 to the straight edge 26, with inturned flanges 3|conveniently and preferably made of the same material as the body of thebolsters and integral therewith.

The bolsters themselves are made of thin material, preferably sheetmetal, of proper thickness and strength and of a metal or an alloy ofmetals that is capable of taking a suitable polish or luster and holdingit permanently.

In order to provide a clearance upon the inner face of the face plateextensions 28 to receive these flanges 3|, the outer side portions 36 ofthe inner face of said extensions will be offset outwardly from thegeneral level of the central portion 31 of the inner face of the endextensions 28, which central portion 31 intimately engages the adjacentouter face of the outer lining. The extent of this outward offsetting ofthe outer side portions 36 relative to the central portion 31 of theinner face of the extensions is about the amount of or slightly inexcess of the thickness of the flanges 3| of the bolsters. There,

is thus provided a clearance or recess 38 between the outer sideportions 36 on the inner face of the extensions 28 and the outer flatface of the outer lining opposite the bolster, which clearance 38clearly appears in the sectional view Fig. 12.

As the preferred and most convenient way of making these bolsters andmounting them upon the face plates is to have the bolsters made witheach flange turned over and back in a straight line toward the otherflange of the bolster (that is substantially in their permanentpositions when they are mounted upon the knife), and after the rivetingoperations at the ends of the face plates are completed, to slip thebolsters bodily onto the projecting end extensions of the face plates,the offset between the parts 31 and 36 of the face plates will extendlongitudinally to the extremity or end of the end extensions 28 so as toallow for sliding the bolsters onto the end extensions without pryingthe flanges 3| out from their desired permanent positions.

In practice this offset may extend to the small area 39 endwise from thecentral portion 31, as indicated on the plan view of the inner'surfaceof the face plates as shown in Fig. 6, but this is a detail that is notessential as long as there is left a clearance 38 for the full length ofthe travel of the flanges along the inner surface of the extensions 28.

I order to make the knife no heavier than necessary and in order to useno more of the plastic material than is necessary, and also in order togive the handle a slight resiliency that is more comfortable to the handthan a solid face plate would be, the body or central portion 25 of theface plates 24 is not made solid butis hollowed out on its inner faceand for most of its extent except at its end boundary walls 40 and atits side boundary walls 4|-4|, and except for an intermediate transverseweb 42 and except for a, small rounded portion 43 adjacent the hole 44provided for the intermediate connecting rivet 23 and except for a crossweb 5| to support the shield plate on one face plate. The relativelylarge extent of these two recesses or hollow portions 45 and 46 is shownbest in the plan view of the inside of a face plate shown in Fig. 6 andalso appears in the somewhat enlarged longitudinal sectional view shownin Fig. 14, which is a central longitudinal sectional view on line |4-|4of Fig. 6. The extent of the recess 45 is further shown in the enlargedtransverse sectional view on line 5| 5 of Fig. 4. The detailed view Fig.16, which is a transverse sectional view on line |6-|6 of Fig. 6, showsthe offset between the central portion 31 and the side portions 36 ofthe end extensions f the face plate.

It will be understood that after the face plates are assembled in placeupon the knife as shown in Fig. '7, the projecting ends of the rivets,when headed over or riveted down, will preferably be left with theriveted material somewhat projecting abcve the adjacent outer face ofthe extended ends of the face plates or crowned over as indicated inFig. 12, so as to make a stronger and more permanent riveted fastening.This is allowable and entirely feasible and proper because the ends ofthese rivets will be entirely covered over and concealed by the hollowbolsters when they are slipped over the ends of the face plates. It willbe understood furthermore that the bolsters 21 will be crowned or curvedsufficient so as not to fit so tightly over the rivets as to require therivets to be ground or trimmed down flush with the adjacent surface, ashas been the necessary procedure heretofore when rivets were placedthrough solid bolsters and their riveted ends were visible and had to bemade to harmonize neatly with the surrounding surface of th bolster.

One way of securely fastening the hollow bolster in place upon the endextensions of the face plate is to put a, small portion of properadhesive such as, for instance, acetate, on the outer face of the endextensions of the face plate just before or as the said bolster is beingslipped into place thereon.

Another method of permanently and securely locking the hollow bolster inplace on the end extensions of the face plate is to form a selflatchinor self-lockingconstruction between the adjacent parts of the bolsterand the extended end of the face plate.

A convenient and the preferred form as I now view it, of making such aself-locking device is clearly shown in Figs. 17 and 18 and consists inhaving a part of one or both of the flanges 3i bent towards the body oroutside crowning portion 41. The part 48 so bent out of line with thegeneral level of flange 3| may be a considerable portion of the width ofthe flange inside the material of the end extension as the depresi sionextends toward the extremity of the extension as indicated in Fig. 18,and so provide a definite upstanding shoulder 59. It will now be obviousthat when the hollow bolster is slid into place the small distorted partor tongue 48 of the flange 3! will be temporarily sprung into line withthe main portion of the flange 3| and will slide along the outer portionof the offset portion 38 until the said tongue 48 reaches andpractically coincides with the depression 49, whereupon the said tongue28 will again spring out of line with the flange 3i and will spring intothe depression 49 and the face 48' of the tongue 48 will more or lessclosely engage the shoulder 50 and thus in an obvious manner permanentlylock this bolster in place upon that end extension. This locked positionof these cooperating parts is plainly shown in Fig. 19.

A further advantage of my plastic face plate is that the outer surfaceof its exposed central part 25 may easily be molded to simulate moreexpensive but less workable material, such as staghorn, and the wholeface plate given the proper color thereof.

The arched or crowning shape of the rounded outer end of my bolsters inpractice holds the outer end of the bolsters in place but as a furtherprecaution I provide a small inturned" ear 52 on the outer extremity ofthe rounded end of the bolster, which ear engages the inner face of theface plate at this point when the bolster is slid into place. It will berecalled that I provided a clearance at this point by having the area 39on the inside of the face plate near the rounded end of the face plateoffset outwardly similar to the offset of portions 36.

Even without the end ear 52 just above mentioned, the hollow bolsterswill be definitely held upon the face plate extensions by the sideflanges 31 of the bolsters, supplemented, if desired, by the adhesiveplaced upon the bolster and an adjacent portion of the face plate, andwith or without the spring-catch or spring-lock tongue 48. In otherwords it will be seen that the securing of the bolster in place upon theface plate is accomplished securely and definitely without having tosolder or weld the bolster to some adjacent metallic part of the knife.This elimination of a soldering operation is a definite improvement oversome heretofore 'used constructions in pocket-knives.

When my invention is applied to a knife the blade of which does not folddown or'move back into a space in the handle, there will obviously berequired no blade spring nor pivot rivet but simply another connectingrivet, and the lining members if used at all, will more properly becalled frame members as there is no recess or space to be lined, but thespace Will be occupied by an elongated shank of the blade. This omissionof the folding or moving feature of the blade however does not preventthe employment of my invention in this class of knives having fixedblades with bolstered handles using face plates.

Figs. 20 to 25, both inclusive, show various modifications where myinvention is applied to articles of cutlery having fixed blades insteadof movable or folding blades, as was the'case in the pocket-knife firstherein described.

Fig. 20 is a side View and Fig. 21 is an edge View of a so-called paperknife embodying my invention. The blade 53 of this paper knife has anelongated shank 54 reaching in fact to the rear end of the handle. Inthis particular knife the formerly called lining members are present asframe members 55 rather than lining members, because there is nowobviously no space or recess to be lined since the shank 54 occupies thespace between said members 55, but the shank 54 extends the full lengthand width of the knife and so forms the real means for supporting andconnecting the blade to the handle.

In this paper knife the face plates 56 have their end extensions 5%reduced in thickness at both the'inside and outside, and also reduced inwidth and length relative to the frame members 55 substantially asalready described in detail with regard to pocket-knives, and the hollowbolsters 51 are sized and shaped to fit over the end extensions 56 afterthe connecting rivets 5'! have been projected through the said shank 54,frame members 55, and face plate extensions 56', and headed over theface plates. Preferably also the bolsters 51 will be provided at theirside edges with inturned flanges 51", which, when the knife isassembled, by projecting into the clearance left between the innersurface of the face plate extensions 56 and the adjacent frame members 55 will positively hold the bolsters in place. The reduction in size ofthe bolster extensions 56 allows the bolsters to be made small enough tofit over the face plate extensions and still align in side view with theframe members 55 and the shank 54.

Figs. 22 and 23 show a paring knife, which illustrates another articleof cutlery employing my invention in the form of hollow bolsters 58,capping both the front and rear ends of the face plates 59 and soconcealing the end-connecting rivets 58, which fasten together thethinned end extensions of the face plates and the shank 60 of the blade6| of the paring knife. Here the shank 60 of the blade forms the solemeans for supporting the blade in the handle and there are no framemembers or lining members. Preferably here also the end extensions ofthe face plates 59 are recessed on the inside in order to provide aclearance between the face plates and the shank of the blade for theflanges 53 present on the sides of these hollow bolsters for holding thebolsters in place, as described in detail in connection with thepocket-knives hereinbefore described. The face plates will also bethinned on the outside and will be narrower on their extended andcovered portions so that the hollow bolsters will make neat joints withthe central portion of the face plates and so that the bolsters will beno wider than the contained or adjacent portion of the shank of theblade. The rounded ends of these bolsters 58 will also preferably beprovided with small integral tongues 58a operating to slip into theclearance between the inner face of the face plate extensions and theadja cent part of the blade shank 60.

Fig. 24 is a side view of a hunting knife and Fig. 25 is a rear edgeview thereof, with the hunting knife embodying my invention in that thesaid handle is composed of face plates 62 having their end extensionsfastened directly to the opposite ends of the full-lengthed and verystrong shank 63 of the blade 64 by the usual rivets. This handle ofcourse does not have a pivoting rivet but it has a connecting rivet 66at each end of the handle which securely fastens the face plateextensions 61 to the shank 63 of the blade. (See sectioned portion ofFig. 25.)

Here again the hollow bolster 65 covers the headed ends of theconnecting rivets 66 and so allows the heads of said rivets to be leftslightly larger and more crowning than has been possible in theconstruction where the rivets came through solid bolsters. This featureof my invention is a decided advantage in a hunting knife where thewhole construction should be strong and sturdy, since the knife is oftensubjected to heavy strain in use.

In this knife also the outside lines of the bolsters harmonize with theadjacent portions of the face plates so as to leave no visible orappreciable ridge between the bolsters and the adjacent portions of theface plates, or between the bolsters and the edges of the shank of theblade. This is accomplished by the face plate extension 61 being reducedin thickness and width, as already described in detail with other formsof knives embodying this invention. Preferably the bolsters of thisknife will also be provided with integral inturned side flanges 68 asshown in dotted lines in connection with the rear bolster of Fig. 24,and also in connection with the rear tongue 69. These flanges andtongues project into a suitable clearance left between the inner face ofthe face plate extensions near their side and rear edges.
